Abstract
Abstract A toy gun or similar device usable with reflective target apparatus utilizes a pulsed light source and a self-contained light detector for detecting light reflected from the target apparatus back to the light detector. The gun includes an audible indicator responsive to the light detector for indicating each time a "hit" is made on the target apparatus, and also includes a resettable counter that provides an indication of the total number of such "hits" achieved in a given time period. The invention also provides a target having a pulsed light source to energize or actuate the light detector.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
191 words
A gaming device, comprising: a hand manipulatable housing; means for emitting a beam of light on said housing; a trigger for rendering said light beam emitting means operative to thereby produce a light pulse; light detecting means on said housing and oriented in a manner to receive light pulses reflected by reflective objects illuminated by said light beam; electro-mechanical means responsive to said light pulse indicative signals for providing an audible and quantitative indication of the detection of said reflected light pulses, said means including a rotary electric motor for rotating a cam and worm gear, a hammer engaging said cam for movement thereby during energization of said motor, a speaker cone assembly in the path of movement of said hammer for producing said audible indication, said worm gear engaging a drive gear formed on a control shaft mounted within the housing, said drive gear including contact means for maintaining said motor energized for a predetermined period of rotation of said control shaft; and counting means responsive to the rotation of said control shaft for providing an indication of the number of reflected light pulses received by said light detecting means.
Claim 2
Dependent Claim
191 words
A gaming device, comprising: a hand manipulatable housing; means for emitting a beam of light on said housing; a trigger for rendering said light beam emitting means operative to thereby produce a light pulse; light detecting means on said housing and oriented in a manner to receive light pulses reflected by reflective objects illuminated by said light beam; electro-mechanical means responsive to said light pulse indicative signals for providing an audible and quantitative indication of the detection of said reflected light pulses, said means including a rotary electric motor for rotating a cam and worm gear, a hammer engaging said cam for movement thereby during energization of said motor, a speaker cone assembly in the path of movement of said hammer for producing said audible indication, said worm gear engaging a drive gear formed on a control shaft mounted within the housing, said drive gear including contact means for maintaining said motor energized for a predetermined period of rotation of said control shaft; and counting means responsive to the rotation of said control shaft for providing an indication of the number of reflected light pulses received by said light detecting means.
Claim 3
Dependent Claim
39 words
The gaming device of claim 1 wherein said counting means includes a threaded portion on said control shaft and a complementary threaded follower for engaging said threaded portion, said follower having a pointer disposed thereon for indicating said count.
Claim 4
Dependent Claim
28 words
A gaming device as recited in claim 2 wherein said follower engages generally one-half the circumference of said threaded portion and is resiliently biased against said threaded portion.
Claim 5
Dependent Claim
30 words
A gaming device as recited in claim 3 wherein said follower is slidingly mounted with respect to and axially movable along said threaded member upon rotation of said control shaft.
Claim 6
Dependent Claim
50 words
A gaming device as recited in claim 4 wherein said pointer is rigidly mounted to said follower to permit said follower to be disengaged from said threaded portion when said pointer is manually depressed against the force of said resilient biasing means to permit said pointer to be manually reset.
